"...if it installs easily it should deinstall just as easily..."
Well, if your distro uses YAST (like Control Panel in Windows) it does
"7.6. Uninstalling the Linux Boot Loader
YaST can be used to uninstall the Linux boot loader and restore the MBR to the state prior to the installation of Linux. During the installation, YaST automatically creates a backup copy of the original MBR and restores it on request, overwriting GRUB.
To uninstall GRUB, start the YaST boot loader module (‘System’->‘Boot Loader Configuration’). In the first dialog, select ‘Reset’->‘Restore MBR of Hard Disk’ and exit the dialog with Finish. In the MBR, GRUB is overwritten with the data of the original MBR."
If you install Windows over Linux, Windows will wipe your hard drive and replace your bootloader with
no backups and
no questions. There
no return from a Windows installation!
No-one is
forced to use Linux y'know (unlike Windows)! If you don't like it or if you're sure the people who've told you that it's awful and terribly difficult are right then please, be Bill's guest! If you're happy with Windows, Tux isn't bothered!
Bill G. is the only one who wants to force everyone to use his OS and apps. and everything and make sure we all live in an expensive MS supervised DRM-ridden world where nothing actually belongs to you anymore.
It's Bill who doesn't want other OSes like Solaris, UNIX, Mac, Linux, AIX, BeOS etc., to be able to talk to Windows, in the hope that he'll kill 'em all off and only Windows and MS will be left. The fact is that if other OSes have problems with Windows networks and printing then it's entirely of Windows making (as the EU Commissioners have so recently and expensively pointed out on two occasions). Nobody wanted MS's volumes of uncommented source code, they just wanted documentation of the communication protocols used (which MS, bizarrely, says it just doesn't have)!
It's still a relatively free world (mostly) - so if you really love Windows and MS, why change? Just keep giving them your money and more and more little bits of your freedom - it's yours to give, after all.
If you know Linux is crap, why, don't go near it and tell everyone you meet what a piece of !!!!e it is!
And if you want Linux to be better then contribute code or ideas or time or money.
To get back to where we were; most distros that I know back up the MBR if they change it and let you restore it, usually from a GUI.
Which is more than Windows does.....
